Test Everything, Everywhere, All at Once With BlazeMeter Performance Testing

Unify performance, functional, and API testing and monitoring with service virtualization and AI-powered test data across 20+ open-source frameworks.

Run Load, API, and UI Tests From a Single Platform

We built a platform that works with the tools you already use, like JMeter and Selenium, while giving them the backbone they need to operate in an enterprise environment. This way, you’ll achieve 30% faster release cycles while reduce 80% in escaped defects.

Start with a BlazeMeter Chrome extension download for quick functional tests, and only move to full load testing when you’re ready.
